摘　　要：针对研究课题制备多环芳烃加氢催化剂,以Ni、Ni-Ce配方,制备了颗粒状的γ-Al_(2)O_(3)载体催化剂。详细的描述了催化剂制备的工艺流程,操作过程中的细节以及注意事项,对加入稀土添加剂的催化剂的活性进行了对比分析评价,同时进行了共浸法和分浸法的比较。通过萘加氢反应,结果表明,Ni-Ce催化效果性能更佳。浸渍方式中,分浸法更优于共浸法。Aiming at the research topic,polycyclic aromatic hydrocarbon hydrogenation catalysts were prepared,and granularγ-Al_(2)O_(3) was prepared by Ni and Ni-Ce formulations Carrier catalyst.The impregnation method was introduced in detail,the process of catalyst preparation,the details and precautions during the operation were described in detail,the activity of the catalyst with rare earth additives was compared and evaluated,and the co-leaching method and the partial leaching method were compared.By naphthalene hydrogenation,the results showed that Ni-Ce had better catalytic performance.Among the impregnation methods,the fractional immersion method is better than the co-immersion method.
